Efthymios Rizos completed his undergraduate and graduate studies at the Aristotle University of Thessaloniki in 2005 and earned his doctorate from the University of Oxford in 2011. From 2011 to 2014, he was a research fellow at Koç University, and at the Netherlands Institute in Turkey. His research has focused on urbanism and cultural history in the Balkans, Greece and Anatolia during Late Antiquity. He is preparing his doctoral thesis for publication as a monograph entitled Cities, Architecture and Society in the Eastern and Central Balkans During Late Antiquity (c. AD 250-600).
Efthymios is a research associate on the Cult of Saints project. His main role is to collect and process Greek textual sources, and archaeological and iconographic evidence from the Greek speaking Christian East. He is particularly interested in the development of shrines and pilgrimage centres, and in their influences upon and from the production of hagiography. He is also interested in the impact of the cult of saints upon the Greek language and in the ways its ideas and practices were codified, transforming the usage and meaning of older words, formulae and expressions.
